Currently wondering why we use RGB when the "red" cones in the human eye are most sensitive to yellow light

    probably cheaper and perhaps you can't make red as a combination of the others

    @matt-jd I'm guessing that second part is mostly why. While a yellow subpixel would activate the long cones the strongest, it would activate the medium ones along with them, making it impossible to actually display red.
